APPARATUS FOR PREPARING FELT FILLEBS FOR MATTRESSES. Application filed August 28, 1926. Serial No. 132,142.

This invention relates to a machine for chine has been provided by means of which preparing fillers for mattresses made of felt cotton linters and other felt stock materials material. can be properly prepared for use in making One of the objects of this invention is the fillers for felt mattresses. We have thereprovision of a novel combination ofelements fore devised a machine which is particularly 55 to form a machine adapted to construct matadapted for this purpose as will appear more tress tillers from cotton linters, and the like. fully hereinafter.

I A still further object of this invention is Referring to the drawings, a closed chamthe provision of a machine of this nature her is shown at 1, provided with side walls m which is adapted to construct the filler of a comprising the parts 2 and 3. The side wall so lurality of layers superimposed one on the is divided into these two parts along a line other and compressed into a compact mass. passing through the centers of the gear A still further object of this invention is wheels shown in Figs. 1 and 6. At each the provision of .a series of carding drums polnt Where the drums extend through the 3 adapted to arrange the stock from which the walls, as shown in Fig. 2, the casing is 85 filler is made in parallel lines, and to prevent notched out along this separating line to the adherence thereto of any ofthe stock. provide openings through which the drums A further object of this invention is'the project. The chamber 1 is supported on a construction of a machine of this nature framework t, which, in turn, is mounted on ml which is relatively simple mechanically, and the roller 5 for convenience in moving the 70 which is so constructed as to be eficient in device from place to place. Mounted in operation. bearing 6 on the framework 4, are the drums These and many other objects which are 7, over which pass the endless belt, chain, or sought by this invention are secured thereby other suitable conveyor 8. The chamber is and will appear in the following description. closed by means of the removable top piece 7 This invention resides substantially inthe or plate 8, to permit of access to the inte combination, construction, arrangement, and rior, if desired.

The drum is provided with a large number of perforations 27,,and a large number of projecting fingers 26, which are suitably secured to the surface of the drum as shown, for instance, in Fig.

Mounted within stantially ported at .the cylinder is a subcircular deflecting plate 29, supeach end by the cap pieces 28, which have projections extending through holes in the end plates 23 and 24 of the carding drum. It will be noted, for instance, in Fig. 3,, that the deflecting late 29 comprises a substantial cylinder wlth a portion of its surface interrupted to form an opening throughout its length. The projection 30, Fig. 2, and as shown its end to provide a square portion 31 which extends into the supporting bar 32, which, inturn, extends throughout the length of the machine as shown in Fig. 1. these drums, all driven by means of the large connecting gears 22, and the smaller idle gears 22, as shown in Fig. 1.

Extending through the projections 30, is a horizontal shaft 33, on which is mounted a. fan 34 of any suitable shape. The shaft-33 is supported in the side bar 32, and a similar side bar 37 6n the other side of the machine,

and has secured thereto, the small gear 35,-

which meshes with a large gear 36, as shown in Figs. 2 and 6. Mounted on a short stud is a gear 21, meshing with the gear 36, and caused to be rotated by a gear over which the chain 18 passes. It will be noted that the extension 30 on the'right hand plate 28 as viewed in Fig: 2- is not provided with a square portion, asis the left hand extension 30. If so desired, and as is shown .in Fig. 3, the right hand cap 24 for the carding There are a plurality of drums may be provided with -a Series of.

Mounted above the conveyor 8, and adjacent to one end is a suitable roller 40 which may be driven by means of the conveyor moving apparatus, or merely by reason pf its contact with the felt material, and is so arranged that the material is compressed as it passes out through the exit in thech'am- I shown in Fig.

The operation of the device is somewhat as follows: The plate 9 is movedto the top of the chamber by means of the gear me of the casing, and material is fed to the chamber through the opening 41, in any suitable manner until the chamber is completely full. The plate9 is then released and allowed to the mass of stock within the casing. electric motor, ed up,
